SAFETY GUIDELINES
0.4 RISKS ASSESSMENTS
Measurements of dose rate were taken by the IRSN, French expert of radioprotection. The intensity of
emission flow is the same one for each type of source used in the analyzers of particles.
The risks assessment from external exposure is equivalent for the sources.
0.4.1 MEASUREMENTS TO THE DIRECT FLOW
Data are the following ones
Radiations of braking Not considered
Dose rate measurement : Contact (naked source) 350µSv/h
Dose rate measurement : 10cm (naked source) 9µSv/h
Dose rate measurement in the plastic box 0.2µSv/h
Dose rate measurement source into analyzer 0.1µSv/h
There is no consideration of amount body dose because the emitted rays are lower than 23cm of length.
0.4.2 CONTROL OF NO CONTAMINATION
The sources are sealed sources. A control of sealing characteristics and no contamination is carried out by
the manufacturer and a certificate of sealed source is joined with each source.
The sources are compliant with ISO2919 classification, they respect C34343 classification
